The use of e-scooters has increased significantly in recent years, but so has the number of accidents involving this relatively new form of transport. At the same time, knowledge about injury mechanisms in this area was still very limited. In the project SURF, funded by Zukunftsfonds Steiermark, the Vehicle Safety Institute at Graz University of Technology (TU Graz) investigated this topic using Human Body Models and derived recommendations to reduce the injury risk in e-scooter accidents. Put on a helmet, decrease speed and get off the pavement As ...

Research conducted by marine biologists from the University of Sydney has found juvenile crown-of-thorns starfish can withstand tremendous heatwaves well above levels that kill coral. These starfish then develop into carnivorous predators that devour reefs just as they begin to regrow. Crown-of-thorns starfish are native to the Great Barrier Reef and found in the Indo-Pacific region, but they are classified as a species of concern because the damage large populations cause to coral is more significant than any other species. ...

Research published in the Journal of Internal Medicine indicates that SARS-CoV-2 infection may worsen lower urinary tract symptoms (LUTS) in men. The study included 17,986 men receiving medication for LUTS within the public healthcare system of Hong Kong in 2021–2022, half of whom had SARS-CoV-2 infection. The group with SARS-CoV-2 had significantly higher rates of retention of urine (4.55% versus 0.86%); blood in the urine (1.36% versus 0.41%); clinical urinary tract infection (4.31% versus 1.49%); bacteria in the urine (9.02% versus 1.97%); and addition of 5-alpha reductase inhibitors, which are drugs prescribed for enlarged prostate. (0.50% versus 0.02%). These urological ...

New research published in Economic Inquiry reports substantial increases in psychological distress in the UK during the first wave of the COVID-19 pandemic. Mental health effects were more pronounced for females; younger individuals; Black, Asian, and minority ethnic communities; and migrants. Also, people who had financial worries, loneliness, or were living in overcrowded dwellings experienced significantly worse mental health deterioration during the first wave. The study used data from the UKHLS, also known as Understanding Society, which is a household panel dataset that captures, among other things, information from adults about their economic and social circumstances, ...

Population outbreaks of the crown-of-thorns sea star (COTS), a predator of coral, can cause widespread coral mortality. COTS are herbivorous as juveniles but then switch to coral consumption as they grow to adulthood. When researchers exposed juvenile COTS to heat stress scenarios at time and temperature durations designed to reflect conditions that cause coral bleaching and mortality, juveniles exhibited tolerance to heatwave conditions well above levels that kill coral. The findings, which are published in Global Change Biology, indicate that juvenile COTS are likely to persist as major coral predators in reefs already vulnerable to the effects of climate change. “This ...

The various neurological symptoms that patients with COVID-19 have experienced suggest that viral infections may increase the risk of neurodegeneration, which could in turn contribute to the development of conditions such as Alzheimer’s disease (AD). A review in the Journal of Neurochemistry highlights the potential mechanistic links between COVID-19 and AD. The authors note that age is the largest contributing factor to AD and COVID-19, and both appear to enhance the effects of the other, with potentially synergistic effects on neurodegeneration. “I believe over the next several ...

Agricultural management has typically focused on increasing yields, but there is an increasing need for sustainable food production that limits negative impacts on the environment. A new study published in Grassland Research provides insights into the potential benefits of diversifying agricultural practices, revealing how different mixtures of plant species can improve production, quality, and conservation. For the study, investigators planted multiple species in different grassland plots, manipulating plant species richness from one to six species spanning three functional groups ...

Identifying different types of body fluids can help forensic experts reconstruct a crime scene, but it’s difficult to do so. In a study published in Electrophoresis, researchers developed a method using two different types of RNA—called microRNA (miRNA) and messenger RNA (mRNA)—to determine five common body fluids. Compared with previously reported single mRNA or miRNA assays, the combination of several mRNAs and miRNAs showed significant advantages for labeling human body fluids. “Our findings indicate that this combined mRNA and miRNA system may provide a scientific ...

It is often claimed that using the snooze button can have negative effects on sleep and cognitive processes, but there has been no direct evidence to this effect. New research from the Department of Psychology at Stockholm University shows that snoozing may actually support the waking process for regular snoozers. It's common to want to stay in bed, potentially even go back to sleep, when the alarm goes off in the morning. The snooze button has been a function in alarm clocks and cell phones for decades and is ...

Now that improvements in technology mean that some robots work alongside humans, there is evidence that those humans have learned to see them as team-mates — and teamwork can have negative as well as positive effects on people’s performance. People sometimes relax, letting their colleagues do the work instead. This is called ‘social loafing’, and it’s common where people know their contribution won’t be noticed or they’ve acclimatized to another team member’s high performance. Scientists at the Technical University of Berlin investigated whether humans social loaf when they work with robots. “Teamwork ...

Proton exchange membrane hydrogen fuel cells (PEMFCs) used in hydrogen vehicles use expensive platinum catalysts to facilitate the oxygen reduction reaction at the anode. There are a vast number of elemental combinations and compositions that need to be explored to develop more efficient and cost-effective catalyst materials than platinum, and researchers are still doing a lot of trial and error in the lab. The Korea Institute of Science and Technology (KIST, President Seok Jin Yoon) announced that Dr. Donghun ...

Collecting accurate weather data in remote and challenging environments like the polar regions and mountains can be extremely difficult. These areas often lack the infrastructure and resources needed for traditional weather stations, and the harsh weather conditions can make it dangerous for humans to access and maintain these stations. Drones can navigate these challenging terrains, gather data, and transmit it to researchers, making them an indispensable tool for addressing these data gaps. Unfortunately, in-cloud flights still pose a challenge, with icing from supercooled cloud droplets that can damage vital drone components, ...

Snoozing, or using intermittent alarms to get in a few more minutes of sleep in the morning, may have benefits for some people, according to research published in the Journal of Sleep Research. In a study of 1,732 adults who described their waking habits, 69% of participants reported using the snooze function or setting multiple alarms at least “sometimes.” In those who snoozed, the average time spent snoozing per morning was 22 minutes, ranging from 1 to 180 minutes. Snoozers tended to be younger than non-snoozers and were more likely to be evening types. Morning drowsiness and shorter sleep were also more common in those who snoozed. In a second ...

A new study led by researchers from the Barcelona Institute for Global Health (ISGlobal), a centre supported by the ”la Caixa Foundation” has shed light on the influence that Endocrine-Disrupting Chemicals (EDCs) can have on children's growth during their early years. The results, published in Environmental Health Perspectives, show that prenatal exposure to some of these environmental chemicals and their mixtures is linked to accelerated Body Mass Index (BMI) gain from birth to nine years ...

The stats don’t lie – the overwhelming majority of start-up companies fail. So, what makes the seemingly lucky few not only survive, but thrive? While good fortune and circumstances can play a part, new research reveals that when it comes to start-up success, a founder’s personality – or the combined personalities of the founding team - is paramount. The study, published today in Scientific Reports, shows founders of successful start-ups have personality traits that differ significantly from the rest of the population – and that these traits are more important for success than many other ...
